Description

Technical Field

[0001] This utility model relates to the field of hooklift truck technology, and in particular to a quick docking and locking structure for hooklift trucks. Background Technology

[0002] Hooklift trucks, as specialized vehicles commonly used for cargo transportation and loading / unloading, rely heavily on the docking and locking structure between the cargo box and the chassis for their core functions. This structure is a key connecting component for cargo transfer, directly impacting the hooklift truck's operating efficiency, safety, and applicability. A quick and stable docking and locking capability allows hooklift trucks to efficiently switch cargo boxes in different scenarios, meeting diverse transportation needs. Therefore, designing a reasonable quick-dock locking structure is crucial for improving hooklift truck performance.

[0003] The existing docking and locking structures of hooklift trucks have many shortcomings in practical applications: On the one hand, some structures lack precise guiding design, and the cargo box is prone to deviation when docking, resulting in a long docking time and requiring multiple adjustments to complete the docking, which seriously affects the efficiency of operation; on the other hand, some structures are complicated to operate and require manual assistance to lock or separate, which not only increases labor costs, but may also lead to unstable docking due to improper operation, and cannot meet the requirements of efficient and safe operation.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figs. 1-3 As shown, a quick docking and locking structure for a hooklift truck includes a frame 1, with multiple docking mechanisms 2 and multiple support seats 3 arranged on the front and rear sides of the frame 1.

[0020] In this embodiment, the docking mechanism 2 includes a docking seat 201, a connecting post 202, a lever 203, a stop bar 204, a docking rod 205, a connecting cylinder 207, a pin 208, a guide groove 211, and a socket 212. The guide groove 211 is located in the middle of the docking seat 201. The lower outer periphery of the docking rod 205 is located on the right side of the guide groove 211, and the upper part of the docking rod 205 is located at the lower part of the cargo box. The upper and lower ends of the connecting post 202 are fixedly connected to the front of the docking seat 201. The front end of the stop bar 204 is rotatably connected to the outer periphery of the connecting post 202. One end of the lever 203 is fixedly connected to the end of the stop bar 204 near the connecting post 202. The socket 212 is located at the rear of the docking seat 201. The connecting cylinder 208... 07 is installed on the inner top wall of the front part of the docking seat 201. The upper outer periphery of the pin 208 is slidably connected to the inside of the connecting cylinder 207. The lower part of the pin 208 is set inside the insertion hole 212. Multiple docking mechanisms 2 are symmetrically arranged on the front and rear sides of the upper part of the frame 1, and there are at least two docking mechanisms 2. A spring 206 is provided at one end of the stop bar 204 near the connecting column 202. The other end of the spring 206 is installed on the inner side wall of the docking seat 201. The left end of the guide groove 211 is flared. A connecting rod 210 is provided at the upper end of the pin 208. The end of the connecting rod 210 away from the pin 208 is set at the upper end of the electric push rod 209. The electric push rod 209 is installed on the inner bottom wall of the rear side of the docking seat 201.

[0021] Specifically, the docking rod 205 at the bottom of the cargo box enters along the trumpet-shaped guide groove 211 on the docking seat 201. During the process, the docking rod 205 pushes the lever 203 to rotate around the connecting column 202, causing the stop lever 204 to rotate accordingly. The stop lever 204 also stretches the spring 206. When the docking rod 205 reaches the preset position, the hook arm no longer pulls the cargo box. At this time, the docking rod 205 is located at the end of the guide groove 211, so that the stop lever 204 is horizontal on the left side of the docking rod 205. Then, the electric push rod 209 shortens, causing the pin 208 to slide down along the connecting cylinder 207 and insert into the insertion hole 212 at the rear of the docking seat 201, forming a longitudinal lock on the docking rod 205, realizing a stable connection between the cargo box and the frame 1. When separating, the electric push rod 209 runs in the opposite direction, causing the pin 208 to be pulled out of the insertion hole 212. Finally, the hook arm drives the cargo box to move, causing the docking rod 205 to slide out of the guide groove 211, completing the separation.

[0022] In this embodiment, rollers 4 are provided on the front and rear sides of the left side of the frame 1.

[0023] Specifically, the cargo box is pulled by the hook arm on the frame 1, and the position of the cargo box is adjusted by the roller 4. When the cargo box is in a horizontal position on the frame 1 under the drag of the hook arm, the main arm of the driving hook arm extends, so that the cargo box moves horizontally on the frame 1.

[0024] Working principle:

[0025] The cargo box is pulled by the hook arm on the frame 1, and its position is adjusted by the rollers 4. When the cargo box is in a horizontal position on the frame 1 under the drag of the hook arm, the main arm of the hook arm extends, causing the cargo box to move horizontally on the frame 1. This allows the docking rod 205 at the bottom of the cargo box to enter along the trumpet-shaped guide groove 211 on the docking seat 201. During this process, the docking rod 205 pushes the lever 203 to rotate around the connecting column 202, causing the stop lever 204 to rotate accordingly. The stop lever 204 also stretches the spring 206. When the docking rod 205 reaches the preset position, the hook arm stops pulling the cargo box. At this point, the docking rod 205 is located at the end of the guide groove 211, so that the stop bar 204 is horizontal on the left side of the docking rod 205. Then, the electric push rod 209 shortens, so that the pin 208 slides down along the connecting cylinder 207 and inserts into the insertion hole 212 at the rear of the docking seat 201, forming a longitudinal lock on the docking rod 205, realizing a stable connection between the cargo box and the frame 1. When separating, the electric push rod 209 moves in the opposite direction to pull the pin 208 out of the insertion hole 212. Finally, the hook arm drives the cargo box to move, so that the docking rod 205 slides out of the guide groove 211, completing the separation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
